The Yuliya mine, owned by the joint-stock company Siberian Copper (formerly the English Yenissei Copper С° Ltd), is located 90 versts in a straight line to the north-west of the district town of Minusinsk in a mountainous area, at an altitude of about 3—3^(1/2)thousand feet above sea level. The terrain consists of a number of separate rather high hills with relatively steep slopes. “Yuliya” lies almost on the border of the steppe (from the north) and taiga (from the south). As a general rule, the northern slopes of the hills are covered with dense growth of larch and birch, while the southern slopes are either bare or only covered with grass. The vicinity of “Yuliya” is composed mainly of crystalline, often siliceous, highly metamorphosed limestones with very disturbed bedding. In many places, the limestones are intruded and cut by a whole system of individual massifs and dikes of igneous rocks - red syenite porphyries and syenites.
In the spring and summer of 1910, on behalf of the Syr-Darya Mining Society, I had to examine the applications and allotments leased by the said company from N.S. Nazarov and located north of the city of Khodzhent within the Khodzhent district. Most of the applications and allotments lie in the foothills of Kara-Mazar ("Black Grave"), the most southwestern spur of the Ala-Tau ridges. Two branches are located in the northwestern foothills of the Mogol-Tau, a separate massif rising on the right bank of the Syr Darya River southwest of the Kara-Mazar mountains.
